Add JARs for new FusionTables API and dependencies
Refactor GData support to separate FusionTables
Restore deprecated Fusion Tables authorization domain
- just for now until we've implemented the new support
Migrate to OAuth2 
- implement OAuth2 for both Spreadsheets & Fusion Tables
- switch cookie name from authsub_token to oauth2_token so there's no
confusion
- implementation is otherwise unchanged - in particular still uses old
Fusion Tables SQL API
Add OAuth2 JARs to Eclipse classpath
Update URLs for new Fusion Table encrypted ID format
Update to rev 17 of Fusion Tables JARs
First pass implementation of new Fusion Tables API - fixes #539

#528
Comments only. No code changes.
More project saving changes for #528
- reduce project retention in memory from 1 hr to 15 min.

- make sure exceptions propagate up to where they can be usefully
handled
Remove stray headless line - Fixes #773
